Keep Your Eyes on the Size: Fund Manager Capacity and Why it Matters MARCH 2013 “There has been a considerable amount of non-sense written on this topic. I believe that every professional investor knows that it is an ironclad law that size reduces outperformance, but I also understand the investment guild’s vested financial interest in muddying the water.” - Jeremy Grantham, Chairman, GMO by David Scobie, Principal Potential misalignment of interests Introduction Is a larger size parcel of shares more difficult to efficiently transact than a smaller trade? If we can safely assume that the answer to this question is “yes”, even if only in some cases, then we have the basis for passing a critical eye over the size of assets managed by equity managers. The issue of capacity is one of the more vexing ones facing the investment industry and also one of the most difficult for investors to come to grips with. Influencing this situation is the fact that: •• Larger managers have an incentive to downplay the issue, and will avoid at all costs an acknowledgement that the performance generated for existing (or potential) clients may be compromised; •• The smallest managers – those who are not near a point where capacity may be a problem – have an incentive to over-emphasise the issue as a means of marketing a comparative advantage; •• Determining a trigger point where the size of assets is excessive is far from an exact science and is unique to individual firms in different markets. Further, often only the portfolio managers themselves are in a favourable position to estimate the full costs. In this sense, what is difficult to measure is difficult to manage (and monitor). The primary purpose of this paper is to highlight that, for the assessment of equity strategies, the level of funds under management (FUM) is an important factor to consider. A small level of FUM is no panacea for successful investment outcomes. However, increasing asset size does bring with it the risk of detrimental effects on performance. Many of the more established, and indeed successful (at least historically), equity managers now have FUM at levels which have reduced their trading flexibility and, in some cases, caused them to invest in higher capitalisation stocks than they might otherwise. This does not necessarily define them as “bad managers”, but it does accentuate issues relating to manager/ client alignment. To state the obvious, businesses generally pursue profit. For an asset management company, which bases revenues as a percentage of FUM, the pursuit of growth is particularly tempting. This is because the marginal cost of managing an extra dollar is small once a critical threshold has been reached. The exercise of “asset gathering” is not necessarily in the best interest of the client, however, and may run contrary to the portfolio managers’ objectives of obtaining the best returns for clients. While a generalisation, this conflict tends to be most evident in large, multi-national organisations where we see less evidence of resolute caps on capacity. The reasons for this are open to conjecture. However, in our experience, most stringent management of capacity tends to exist in firms where there is an absence of controlling external shareholders, where management is relatively connected to the day-to-day investment function, and where the firm is a niche operator.1 1 These circumstances tend to apply to so-called “boutique” firms. However, such status alone in no way ensures conservative capacity management or superior performance. Further discussion on the merits of boutique managers is contained in “Riders on the Storm – Re-examining the Case for Boutique Managers”, Mercer, July 2009. 2 Keep Your Eyes on the Size: Fund Manager Capacity and Why it Matters Whatever the organisational context, we regard it as highly desirable for firms to put staff incentive structures in place which have fund performance outcomes as the dominant success measure (as opposed to focusing on asset or revenue growth). Liquidity and the realities of trading stocks Amplifying the capacity conundrum is that, in Mercer’s experience, quite often the managers who have surpassed reasonable capacity levels have difficulty coming to grips with the issue. This is because the implications of a firm acknowledging that it has allowed assets to build up to an excessive level are seriously adverse from the manager’s perspective. The liquidity of a security refers to how readily it can be bought or sold. It is implied by factors such as the security’s market trading volume, bid/ask spread, number of shareholders and diversification of the shareholders. It is worth noting that the average trading volume of a stock on an exchange may disguise its true liquidity. Many stocks tend towards a low median trading volume but with a higher average distorted by occasional large trades. 2 “Size is the enemy of (fund manager) performance. If you limit assets under management, you have a much better chance of beating the market. But asset gathering improves profits. So what happens? Almost invariably, managers are out there gathering assets, trying to increase profits, and it comes at the expense of generating investment returns” The ability of a fund manager to trade effectively depends upon the size of active positions held compared to the liquidity of the market. In simple terms, should the number of shares scheduled to be traded exceed the available liquidity of the market, completion of the transaction will likely take more time and may not be as efficient. Too much money chasing too few shares drives the price up. Similarly, immoderate selling over a confined timeframe creates a surplus of sell orders in the market place with consequential downward pressure on market prices (an especially troublesome scenario when a manager’s stock positions are well known in the marketplace).3 Both these outcomes are undesirable from a portfolio perspective. – David Swensen, CIO, Yale Endowment Fund 2 A more extensive discussion of this topic is contained in “Lost in Transition? Factoring in Costs Before Switching Managers”, Mercer, July 2011. 3 This is a particular hazard where a firm suffers a widespread loss of investor support for any reason and is obliged to liquidate market positions within a relatively short space of time. 3 Keep Your Eyes on the Size: Fund Manager Capacity and Why it Matters Transaction costs It is important to recognise that transaction costs in equity markets are made up of both “visible” cost elements that are relatively simple to observe and measure, and “invisible” cost elements that are a lot less so. “Invisible” costs There are less transparent transaction costs that also need to be considered: “Visible” costs The most transparent cost elements include: •• The levy paid to market operators to undertake the •• Market impact.

This •• Taxes on share transactions, particularly stamp is reflected in the actual movement of the share price duty in some countries such as the UK; relative to the broader market until the intended orders •• The bid/offer spread, i.e. the difference between have been filled or withdrawn; the price at which a broker will buy and sell a stock. • • Opportunity cost of not trading.

Trade Execution Bid/offer spread Impact on Market Price Keep Your Eyes on the Size: Fund Manager Capacity and Why it Matters ANALYSING LIQUIDITY Some managers, and some relatively simplistic transaction cost measurement services offered by custodians, aim to monitor indirect costs across their dealing desks. They do this through reference to the average price at which buy or sell transactions are executed against the volume-weighted average prices (known as VWAP) of the relevant stocks for the day on which the trade is executed. This type of measure does, however, understate indirect transaction costs for buy and sell orders filled over a number of days, and does not make any attempt to capture the opportunity cost element. Specialist third-party firms also exist which aim to be more sophisticated in measuring transaction costs, including attempting to measure the impact over a number of days by monitoring the stock price before and after a purchase or sale.4 One way in which Mercer considers liquidity is through holdings-based analysis; in particular, with reference to the time it would, in theory, take a fund manager to “trade back to cash” (liquidate the entire portfolio) or to “trade back to benchmark” (neutralise active positions). We do this by assigning an applicable portfolio size for a manager and presuming an ability to trade a certain proportion (say 20%) of each share’s daily market volume. As an example, the chart below for a particular fund manager shows that, on the basis described, it would take over 5 days for 90% of the portfolio to be traded back to benchmark. This only gives a broad indication of portfolio liquidity as it does not account for potential placement of block trades – “off-exchange” transactions can be a meaningful way of deriving liquidity. However, it is a useful measure of comparison for the same manager over different points in time, or against different managers operating in the same sector. The analysis also identifies particularly illiquid securities in the portfolio which may be hardest to sell down, and those benchmark stocks not held in the portfolio which would be most difficult to acquire.

The market-making services of these intermediaries, which help provide liquidity in markets, are not as prominent as has been the case historically. 4 5 Sentinel – a division of Mercer – is one such provider of independent transaction analysis. Keep Your Eyes on the Size: Fund Manager Capacity and Why it Matters Swimming in dark pools A notable development in the global trading environment over the past decade is the use of “dark pools” by institutional investors. Dark pools are trading venues in which orders can be placed without making them visible to the market. The trades are usually reported to the exchange after orders have been executed. Varying views exist as to whether dark pools actually provide a net benefit to market liquidity. Proponents argue that being able to buy or sell large blocks of securities without “showing your hand” to others avoids market impact as neither the size of the trade nor the identity are revealed until the trade is filled. However, dark pools have been criticised for their lack of transparency and because the inevitable fragmentation of trading could lead to less efficient pricing in traditional open stock exchanges. The point of low return factors impacting on capacity levels A generalisation as to an exact dollar number, or percentage of available market capitalisation, before portfolio performance is impeded by asset size does not exist. This is due to the fact that investment managers have different approaches to generating outperformance and invest in varying sectors and regions. However, what we can say is that the extent to which the implementation of an investment process is compromised by high levels of assets will be influenced by: •• The level of stock turnover generated by the process, with higher turnover trading-oriented processes being more sensitive to FUM. This may also apply when the fund is liable to trade in and out of cash; •• The market capitalisation bias of the mandate, with strategies focused on smaller cap (often less liquid) stocks being more sensitive to FUM; •• The style of the process, with growth styles incorporating a bias to momentum being more sensitive to FUM than value or contrarian styles. Value managers argue that they look for stocks that are out of favour and have relatively abundant supply, with the expectation that they can exit painlessly when the value is recognised and new buyers emerge. In that sense they are “liquidity providers”. Conversely, growth oriented managers tend to acquire “in demand” stocks. They may be more subject to momentum factors and exacerbate market impact through their trading strategies; 5 6 6 •• The stock universe, with narrow or restrictive mandates giving managers less lee-way to allocate the FUM;5 •• The level of stock concentration in the portfolio. Where the intention is to operate a “high conviction” strategy with a limited number of securities, this will tend to use up FUM capacity to a greater degree6; and •• Dealing capability, with unsophisticated execution techniques curbing the manager’s capacity earlier than might otherwise have been the case. Managers exhibit varying efforts in monitoring and minimising their market impact. Those managers wanting to reduce their trading impact may make use of a dedicated centralised dealing team, basket trades, electronic crossing networks or patient trading disciplines. The lifecycle of the strategy is a contextual factor. Firms that are in their early stages, with low FUM but growing, are in a position to rebalance the portfolio using cash inflows. This keeps their security turnover, and hence trading impact, artificially low. This feature is lost as growth of the firm plateaus. Expanding the mandate universe will serve to lessen liquidity issues but may diffuse the area of focus sought by the client. This is one reason why high conviction strategies tend to charge a higher investment management fee. Keep Your Eyes on the Size: Fund Manager Capacity and Why it Matters Taking it to the limit – the consequences of excessive FUM The following are some possible consequences of a fund manager operating with excessive FUM: •• The dilution or sacrifice of best ideas because of an inability to fully execute at a reasonable price or timeframe (some ideas are particularly time sensitive); •• The manager is forced to lower the portfolio turnover, i.e. artificially increase the holding period; •• A change in investment style caused by an inability to trade positions due to liquidity constraints, e.g. style drift against, say, growth and momentum; •• The portfolio will tend to have larger cap bias over time as small and mid cap stocks fall out of the investable universe; •• The portfolio will start to more closely resemble the index as a greater number of stocks are bought; •• Increased exposure to already-owned liquid stocks to maintain style, thus increasing company specific risk; •• A potentially higher involuntary cash exposure; •• Forced trading when liquidity is lacking which is likely to have an adverse impact on the stock price. Should client support falter and the manager start to lose large accounts, a snowball effect can be created7; •• If not all client portfolios are able to be replicated because a firm can’t buy or sell enough of a certain stock, a loss of homogeneity will occur leading to potential dispersion in returns; and •• With large FUM, the potential breadth of the investor base is such that, unless carefully controlled, key investment staff might be obliged to spend excessive time on client relationship activities. Some managers with excessive FUM have been able to get away with it for a while during periods when they have gotten most of their investment decisions right. The periods when they tend to “pay” for higher FUM are those when they get it wrong, and what would normally have been a brief period of moderate underperformance becomes extended. The tendency is that instead of the manager getting rid of poor stocks immediately that realisation is made (as they would have done when they were smaller), they hang onto the stocks in the hope that they might somehow turn around, knowing that if they tried to sell them they would be paying a heavy market impact penalty. This creates a tremendous opportunity cost, which doesn’t get picked up by transaction cost measurement systems. Not too big but not too small An implication of the discussion so far is that, all things being equal, a manager may have to become better at generating good investment ideas (or more clever about implementing them) to sustain a given level of outperformance as its volume of FUM grows beyond a certain tipping point. This can be thought of as a “handicap” that a larger manager has to give away to a smaller manager in order to match its performance. This needs to be weighed up against any perceived benefits from the broader and more expensive pool of investment resource that the larger manager can bring to the table. A firm with very low FUM is of little use to its clients if it cannot achieve a critical mass which enables it to survive as a business. While it is common for a new firm to go through an initial period of generating losses as it becomes established, this cannot go on forever – office costs need to be paid, resourcing needs to be adequate and staff reasonably incentivised. Where performance fee structures are prevalent, times of strong portfolio returns versus benchmark will boost profitability but the firm also needs to withstand those inevitable periods where returns are less favourable. 7 As the manager is forced to exit the securities for cash redemption purposes, the increased supply of the securities may depress the stock price and thus have a negative impact on performance, which could lead to further client departures. 7 Keep Your Eyes on the Size: Fund Manager Capacity and Why it Matters Part and parcel of a fund manager developing a sustainable business is having a diversified client base. In practical terms, this means the firm not being over reliant on the “hire/fire” decisions of a relatively small number of investors or having too many similar types of clients. This is not always readily achievable, particularly during a firm’s start-up phase or where FUM is modest. This again points to some pragmatism being appropriate when considering what levels of FUM are acceptable. Larger firms can be more readily relied upon to be in business not just for the next 12 months but for some years to come. Some practical observations “Unlike many business buyers, Berkshire has no ‘exit strategy’. We buy to keep. We do, though, have an entrance strategy, looking for businesses that meet our criteria and are available at a price that will produce a reasonable return… If you have a business that fits, give me a call. Like a teenage girl, I’ll be waiting by the phone.” – Warren Buffet, Chairman, Berkshire Hathaway In Mercer’s experience, smaller managers understandably often claim that their small size enables them to be more “nimble” or “flexible” in the market than larger managers, thereby giving them an advantage in their quest for outperformance. Meanwhile larger managers generally agree on two things: firstly, that volume of assets can hinder performance if it gets too high and, secondly, that they are not yet large enough for their performance to be significantly hindered by this factor. Lest this paper imply otherwise, there have been many examples of managers delivering strong returns even when their FUM are substantial. In some cases the level of stock-picking skill is such that higher trading costs can be absorbed while still generating value-added. In other cases a valid investment philosophy may be predicated on consciously trading off liquidity for controlling or substantial stakes in companies owned. This can bring about the benefits of strong information flow and degree of influence, and lend itself to an “activist” stance. It is a longer term approach, however; typically associated with low turnover. It is best suited to firms with a strong reputation and a highly diverse and/ or loyal investor base so as to minimise the likelihood of material unexpected redemptions. We should also emphasise that it is by no means a rarity for fund managers to close their equity products to new business to protect investor interests, or stipulate that they will cap the level of FUM at a pre-determined level. In the former case, a subtle but important distinction can be made between a “soft-close” and a “hard-close” policy. As typically interpreted, a soft-close means that a firm will not take on monies from new clients but will generally accept flows from existing clients. While sounding positive on the surface, this approach will fail to meaningfully address a capacity problem where the scope for flows from existing clients remains material. A true “hard close” policy places a more stringent constraint on FUM levels and is one we witness with less regularity. Among large cap or all cap managers, the closure point for a US, UK or Australian domestic equity product is most commonly set somewhere between 0.5% and 1% of the market capitalisation of the relevant market. That said, it is not uncommon for some firms to attempt to manage 1-1.5% of the market or more. In such cases, Mercer’s general approach is for the onus of proof to rest with the fund manager in terms of size not compromising returns. It is worth noting that no fund manager can materially grow its business without providing competitive returns for clients over the medium term. In that sense there is 8 Keep Your Eyes on the Size: Fund Manager Capacity and Why it Matters scope for a self-correcting mechanism to kick in – an alert client base will react by terminating the firm’s services and the level of FUM will ease off to more manageable levels. Finally, it is perhaps unsurprising that we have occasionally seen investors (and fund managers) identifying effective capacity management as an ethical issue, i.e. being seen to be doing the right thing by the client. Suggestions for addressing potential problems To address the issue of capacity, institutional investors can consider the following actions: •• Recognise that it is very much a rarity for an equity manager to admit to having too much money under management. Some will say that capacity is not an issue for them, and some will say they are “closing in” on a limit but it has yet to influence portfolio returns. Typically the managers will sound convincing, but not all will be accurate; •• Pro-actively monitor the asset growth of incumbent managers and be conscious of how this might affect their fund performance given the expected investment style and process. Being aware of how much they manage within the asset class in related strategies is also important, e.g. holdings in emerging market- and small cap-dedicated funds may affect global portfolios, and vice versa; •• Use measurement tools such as the portfolio’s “active share” over time to help flag whether the strategy is increasingly mimicking its benchmark;8 •• Give consideration to the use of performancebased fees as a means of improving the alignment between the interests of fund manager and client. While this is not necessarily a full solution, and at times may entail paying a higher total fee, a welldesigned fee structure will negate managers being rewarded for index-like performance and encourage managers to constrain asset growth; •• Split assets across a range of managers and styles so as to reduce exposure to specific FUM capacity issues; •• Review, and possibly terminate, managers considered to be facing liquidity concerns (or managers who refuse to seriously address potential concerns); •• Appoint managers who have demonstrated a commitment to controlled asset growth in the relevant investment sector. A suggested approach from a fund manager’s perspective is: •• Address the capacity issue head-on as a longerterm business issue. Ignoring growth constraints is not a strategy. Plan for it before it becomes a reality; •• Give weight to the views of investment team members who have the best chance of knowing whether the level of FUM may be affecting portfolio performance; •• As seen as appropriate, decline additional business and/or limit the annual new cash flow into the strategy. A soft-close may be implemented as an initial measure to reserve capacity for existing clients; •• In some cases the only proper response is a hardclose. While this is not an easy business decision, the upside in terms of credibility with clients and other stakeholders is not to be under-estimated; •• Because the threshold at which FUM has a materially negative effect on performance is not easy to gauge with precision, erring on the side of conservatism is an appropriate stance when adopting a policy; •• In some cases it may be feasible to offer complementary strategies which do not cannibalise alpha generation from existing products. For instance, some firms seek to expand their business without impinging on value-added by offering indexed strategies alongside their active business. Others will employ different, complementary teams such as an active growth and/or an active value team which operate independently (the holdings of 8 “Active share” measures the portion of a portfolio’s holdings that deviates from its benchmark index. A reducing figure over time implies that the manager is taking less active positions. 9 Keep Your Eyes on the Size: Fund Manager Capacity and Why it Matters the company still have to be aggregated to lodge substantial shareholder notices). The above said, a real concern with this option is that offering alternatives may compromise the manager’s original investment style that had led to its success over the years; •• Recognise that there is only a finite amount of time that key investment staff can spend on assorted client servicing requirements or new business pitches before their core task is compromised; •• Be cognisant of the scope for changes to the firm’s culture or dynamics as it grows. For instance, staff may need to splinter their responsibilities, re-establish reporting lines and/or be spread across different floors or geographies. Does this alter the “secret sauce”? Is it still a tight-knit team?; •• Finally, ensure that investment staff are focused on strong performance and that their remuneration is clearly steered toward that outcome. 10 “We have decided to close temporarily to all clients in order that we may further consider the implications of becoming a midsized asset manager without prejudicing the outcome of our deliberations by continued growth ... Our focus should always be on managing existing funds well, not on gathering funds. There seems to be a fundamental tension between this principle and remaining open.” – UK-based global equity manager. Keep Your Eyes on the Size: Fund Manager Capacity and Why it Matters Closing comments To summarise, it is inevitable that there are associated costs, some more readily identifiable than others, with increasing assets under management. In general, transaction costs will increase in equity portfolios as the level of assets increase, regardless of the competence of the firm’s traders. Eventually a point will be reached at which the impact on performance of the higher transaction costs becomes significant. Direct costs such as taxes and commissions may not go up (they may even decrease), but indirect costs such as market impact and opportunity costs of trades not implemented will increase. There is nothing that managers can do about this apart from closing to new business well before they reach the point at which they become affected. Mercer does not believe that there is a generic “magic number” beyond which a manager should not grow its FUM. A concentrated portfolio focused on large cap stocks has different limits to a more diversified portfolio or one that is focused on smaller capitalisation companies. Indexed and enhanced index strategies have higher limits. Managers that employ a number of different portfolio managers or different products with different investment styles have different limits again. The targeted or actual level of portfolio turnover also affects the potential constraints lower turnover styles having higher ceilings than more aggressively managed portfolios. Mercer considers the volume of FUM as a distinct characteristic when assessing a fund manager. In doing so, we find that an analytical approach which encompasses both quantitative and qualitative aspects yields the most useful information. We look for signs that managers are dealing with growth in a realistic, transparent and planned manner. In that way, good quality managers have the best chance of remaining good quality managers – the prize for keeping their eyes on the size.9 9 Input into the preparation of this paper is acknowledged from the following Mercer colleagues: Deb Clarke, Matt Reckamp, Andy Barber and Philip Houghton-Brown. 11 Keep Your Eyes on the Size: Fund Manager Capacity and Why it Matters Contact [email protected] ©Copyright 2013 Mercer LLC.
